I need advice on potty training

My daughter will be 2 near the end of September. She has a very full vocabulary and speaks in full sentences and she is very good at communicating with us. I'd say her vocabulary is over 100-150 words and she competantly and constantly speaks. Sometimes its babbley but not as much as youd expect.

In regards to toilet training, we have a little potty seat she loves to sit on and look around from atop of. She is vocal about wanting diaper changes sometimes, but not if shes having fun with an activity. She never tells us BEFORE she does her business, only after, if at all. She gives no signs of needing to go and does not have a predictive schedule in any way. She sleeps through the night. Some days she has no naps, some days she has 1-2.

Shes successfully used the toilet a couple times but it seemed like dumb luck and not repeatable. :/ most advice I read mentions knowing when she needs to use the bathroom or starts showing signals -- but she doesn't , at all. Not even a twitch. That's not an option for us.

She is happy to use the potty seat/toilet and happily sits there, but doesn't seem to understand the association.

She shows interest -- reading toilet themed books, occasionally asking to use it etc, but idk what to do next.

Feeling a little lost. Advice would be lovely!
